How to figure roof pitch height.
Technically roof pitch is the ratio of total vertical roof height the rise to total horizontal distance from wall to wall the span.
As a reminder please don t forget to add height of rafter thickness of roofing material and ridge vent to the number that you ll get using our calculator.
Carpenters measure roof pitch as inches of rise per 12 inches of run.
You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
The pitch of a roof determines the height of the ridge board that runs the length of the house.
